A CORPORATION OF MASSACHUSETTS vIsIBLE STRIP INDEX Application filed une 25,

This invention relates to index devices and i particularly to indexes of the so-called visible v be carried type wherein a seriesofcards or strips are assembled in Overlapping relation with their respective margins exposed to display names or other identifying subject matter. The invention has to do particularly with the construction and arrangement of the index strips and its principal object is to provide a simple and unique index of this type comprising a series of interlocked, overlapping strips adapted to display typed, printed or written index ,data' along theentire width of the exposedstrip margins and to constitutean interconnected assemblage which may readily about as an individual composite sheet or which may be filed in a drawer or attached upon a verticalsupport for ready reference. Other more specific objects reside in the details of structure hereinafter de scribed and-pointed out in the appended. claims. I

sired length and width, Each strip has one or more tongues or tabs and one or more corresponding slots or apertures whereby, when the strips are detachably interconnected to form the assembled index, the tongue or tongues of one strip are removably received and retained within the complemental slot or slots of the adjacent strip of the series, thereby to interlock and space the strips rel- 6O projecting one beyond anothen.

A pair of tongues having their bases in the same line and substantially parallel to one. longitudinal edge of the stripand having their ends projecting in opposite directions are preferably provided near the respective ends of each strip and these tongues are preferably inserted into corresponding slots in the next adjacent strip by flexing the Strip transversely so that, when the strip is re leased, the projecting ends of the tongues extend beyond the outer ends of the respective slots effectively to interlock the strips against casual displacement. The strips may be tilted or swung upon the hinge-joint'thus formed, yet the units are so interconnected that the assembled composite sheet index is self-sustaining without the necessity of pro- I viding expensive metal frames or other index holders.

. I Each of the strips 10, illustrated in Figs. 1 to 3 consists of a single thickness of cardboard and has a pair'of tongues 11 projectingfrom its upper edge and a pair of apertures or slots 12 disposed below said tongues and substantially parallel to said upper edge. The tongues have outwardly projecting ends 13 which look behind the stripnext above at the outer ends of the respective slots thereof, when the strips are assembled as aforesaid in overlapping relation. ,As thus arranged strip is exposed to display names or other data appearing thereon, and it will be observed that the typing, or printing may be carried to the extreme 7 Furthermore, it will be apparent, as indicated in Fig. 3, that the normally concealed lower portion of any of the vtongues 11' of the topmoststrip of the series. The sheet 15 which serves as a backingfor said stripmay alsohave a pocket for a removable label, as shown in the drawmg. 7 v Fig. 3 illustrates another form of backing or sheath which may be opaque or transparent, comprising a folded sheet providing a front flap and a rear'flap 26, the frontflap having slots 27 to receive the tongues 11 of the strips 10; and shows thethree bottom strips in theseries swung upwardly upon the hing topermitinspection of or the making of notations upon the lower, normally concealed portion 10 of the fourth strip from the bottom. Obviously the concealed portion of any selected strip may be thus quickly and 1 easily exposed without disturbing the arrangement of the-interlocked strips. the upturned strips are released-they will fall back into normal position without manual adjustment.

' ness unit strips 18 each consisting ofv a strip of paper folded along its central longitudinal:

I The modified form Oma illustrated-in Figs. f to 7 comprises a seriesof double thickline to provide a pair of similar leaves which are preferably united to each other along theirlower edges by a suitable adhesive.

Downwardly'extending tongues 19, similar in their essential characteristics to the tongues 11 of the strips 10, are stamped out or cut from the body of the. front leaf ofv each strip and are adapted to interlock with v series. The bases of the respective tongues '19 are preferably-spaced below and parallel that in the resulting corresponding slots 20 provided at the upper folded edge of the strip next below in the to said folded edge, so assemblage (Fig. 7) the upper margins of vthe interconnected, overlapping strips are exposed and the strips may be swung on the hinge-joint as above described.

I The strips 18 may be convenientlyformed without loss ofmaterial from a continuous paper sheet stamped out and perforated as Figs." and'5. Suitable lines may 'be printed on the sheet to indicate the fold shown in line21 and the margin line 22 so that the margins maybe typed before the individual strips are separatedupon the perforations 23. The rear face of the sheet is preferably 'gum'med as indicated at 24: (Fig. 5) along one or bothrsides of the perforations 23,

whereby the bottom margins of the detached folded strips may be quickly and easily-joined together bymoistening the adhesive area.
